Knowledge of the particle number is critical in many of our applications. In trying to rationalize membrane ‘clogging’ by particles for example, it is wise to compare the particle density to pore density at the membrane. When conjugating protein to NPs, it is important to work in a molar excess of protein. In using nanoparticles…
Mary Lee and I performed a quick test to determine the efficacy of different surfactants at reducing agglomeration between IgG and 20 nm fluospheres. Each solution is a combination of 50 uL 10 mg/mL IgG (in PBS) + 50 uL 20 nm red Invitrogen fluospheres + 500 uL of surfactant. We used 1 x PBS…

Hi all, Today I would like to briefly mention the important parameters to consider when saturating a substrate with proteins by simple adsorption. More specifically, the concentration and time required to fully saturate a substrate ares estimated for systems with different geometry (see the PDF attachment): [NRG] surface adsoprtion The first-order approximations entailed in the above…
We still need help with NanoDays http://doodle.com/paq66krxtf7mt6tk There are two time slots: 10:45am-2pm 1:45-4pm Please wear your I Love Nano shirts from last year. I have a couple more size Medium and one size Small. The Rochester Museum & Science Center is on the corner of Goodman and East Ave.
Katia Lyubarskaya in Alex Shestopalov’s lab has been testing different surface conditions of oxidised NPN membranes. I’ve placed her data below. (We used chips from wafer 1070) We started by looking at chips that received different chemical/plasma/thermal processes to create an oxide layer. The thermally treated sample has a significantly higher Oxygen peak, but…
In order to test the efficacy of any dialysis treatment, we need induce uremia in our animal model. We choose to forgo the surgical approach of performing a 5/6 nephrectomy via ligation for the simpler diet based approach. Feeding the animals a diet containing adenine is meant to raise the level of urea in the…
